This bind_dn format is default one used in iRedMail + OpenLDAP. Do you have the same structure in Active Directory? I'm afraid not.So, please modify it to fit your Active Directory structure, or, follow our wiki tutorial to use a global bind dn instead.http://www.iredmail.org/wiki/index.php? … be_webmail

P.S. If there's a tutorial, please follow it strictly first. if it doesn't work for you, then tune it.Many users reported this or that issue, all are caused by not following our wiki tutorial STRICTLY. Don't make me feel i'm wasting time to write detailed wiki tutorials.[THIS IS NOT A BLAME, PLEASE CONSIDER IT AS A REMINDER.]

"invalid credentials" always means incorrect bind dn or bind password. So please check them in your Roundcube config file. If you aren't quite sure what the root cause is, show us your address book related settings here to help troubleshoot.

Port 143 is not enabled by default, please use port 993 (IMAP over TLS) instead.

I'm trying to setup iredmail e-mail server and integrate it with Samba 4 domain controller.So far, so good using this manual: http://www.iredmail.org/wiki/index.php? … y.iRedMailFirst of all could not make dovecot start, because of vmail group was missing. So created a group called vmail (groupadd -g 5000 vmail).I'm getting to the point where i should telnet to localhost on 143 port, but all the time i get an error message "* BYE Internal error occurred. Refer to server log for more information."Have no idea where to look for some ideas
